Which aspect is crucial for the health of cities in regard to urban sustainability?

The health of cities in the context of urban sustainability significantly hinges on balancing social equity with ecological health. This approach recognizes that sustainable urban development must address the needs of all community members while also protecting and restoring the environment.

In a sustainable urban environment, social equity involves ensuring that all individuals have access to necessary resources, services, and opportunities, such as affordable housing, public transportation, and green spaces. This contributes to a higher quality of life and strengthens social cohesion, which are essential for a city's overall health and vitality. On the ecological side, maintaining a balance means implementing practices that protect natural resources, promote biodiversity, and address climate change.

When cities focus on both social equity and ecological health, they create resilient urban spaces that can sustain future generations. This integrated perspective leads to more effective urban planning and policy-making that considers the interconnectedness of social solutions and environmental stewardship.

In contrast, the other choices emphasize aspects that undermine urban sustainability. High levels of environmental degradation directly threaten the health and livability of urban areas. Relying solely on fossil fuels leads to pollution and resource depletion, jeopardizing long-term sustainability. Lastly, focusing only on economic outputs often neglects the social and environmental dimensions necessary for a well-rounded and lasting urban development strategy
